Samsung has been hard at work on Tizen—its own mobile OS that might one day compete with Android and iOS—for a while now, and today saw the release of the first Tizen tablet, a 10-inch slate from Japanese company Systena Corporation. Tizen Indonesia reports that the device will be offered as part of a development kit so that app and software creators can get a feel for working on the new platform.

The 10-inch tablet comes equipped with a 1,900 x 1,200-pixel display, a quad-core processor clocked at 1.4GHz, 2GB of RAM, a 2-megapixel camera and 32GB of storage with microSD support. It runs Tizen 2.1 and comes in white and red models. The South Korean company is expected to unveil the first official Tizen smartphone during the Samsung Developers Conference, which takes place this weekend in California.

Samsung and Intel have spent the last year quietly working on Tizen, an HTML 5-based OS that incorporates aspects of the South Korean company’s earlier operating system bada. Leaked screenshots from earlier this year showed the software was coming along nicely, though we won’t know anything for sure until Samsung makes an official announcement
